2-[Carbamo­thio­yl(2-hy­droxy­eth­yl)amino]­ethyl benzoate: crystal structure, Hirshfeld surface analysis and computational study

The title di-substituted thio­urea, C(12)H(16)N(2)O(3)S, has the hy­droxy­lethyl and ethyl benzoate substituents bound to the same amine-N atom, and is twisted, having a (+)syn-clinal conformation with the N(amine)—C—C—O((hydroxyl, carbon­yl)) torsion angles of 49.39 (13) and 59.09 (12)°, respectively; the dihedral angle between the almost planar CN(2)S core and the pendent benzene ring is 69.26 (4)°. In the crystal, supra­molecular layers propagating in the ac plane are formed via a combination of hydroxyl-O—H⋯S(thione), amine-N—H⋯O(hydroxyl, carbon­yl) hydrogen-bonds. The layers stack along the b axis with inter-digitation of the benzene rings allowing the formation of π–π stacking [inter-centroid separation = 3.8722 (7) Å] and parallel C=O⋯π inter­actions. A computational chemistry study shows the conventional hydrogen bonding in the crystal leads to significant electrostatic stabilization but dispersion terms are also apparent, notably through the inter­actions involving the benzene residue.
